Grid interconnections in Africa will help achieve the operation of solar and wind power bases in North Africa jointly with the hydropower bases in Central Africa and the solar energy bases in Southern Africa to meet rising power demand in Africa and provide a robust grid at the sending end for solar energy exports from North Africa, shaping a new energy scenario marked by the delivery of electricity from north to south, mutual support for electricity flows between east and west, transmission of power northward to Europe, and interconnections with Asia to the east. To promote hydropower development of the Congo river, the government of South Africa approved in 2012 the draft provisions for developing the Grand Inga Project in partnership with the Democratic Republic of the Congo. Under the project, plans are afoot to employ large-capacity, long-distance power transmission technology to deliver electricity to South Africa, Egypt, Nigeria, and other nations after meeting Congo's power demand.This project to deliver power to North Africa can reach as far as Southern Europe and the Middle East. Hydropower development of the Congo River will create favorable conditions for the construction of an interconnected power grid in Africa. In the future, solar energy bases in Egypt, Algeria, and other North African countries will deliver electricity to East Africa and West Africa. The transmission channels will then extend southward to interconnect with Southern Africa, forming a horizontal backbone stretching from east to west as part of Africa's wider interconnected system. Hydropower generated in the Nile River Basin will be supplied to Egypt to the north and Tanzania to the south. While supplying power to Central Africa, the hydropower bases in the Congo River Basin and the Zambezi River Basin will jointly operate with the wind and solar energy bases in the north and south to promote continentwide integration of renewable energy and to supply power to West Africa and Southern Africa.

In the future, North Africa, Central/East Africa, West Africa, and South Africa will evolve into four major power grid regions in Africa, to further develop into a larger, continent-wide grid system through interconnections. North Africa's regional power grid, an important electricity exporter of Africa, covers primarily local solar and wind power bases, and load centers to the north. Central/East Africa's regional power grid, also an important electricity exporter of Africa, comprises hydropower, solar and wind power bases. West Africa's and South Africa's regional power grids carry large domestic loads, making them major power importers in the future. See figure for Africa's transnational grid interconnections.
